Infineon Technologies CY96F346RWBPQC-GS-UJE2

Overview

CY96F346RWBPQC-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock domain support, 416 KB Flash (Flash A), 16 KB RAM, two CAN 2.0B interfaces, 24-channel 10-bit SAR ADC, and integrated voltage regulator. It operates at up to 56 MHz via on-chip PLL (17.8 ns instruction cycle), supports LIN/USART/I²C peripherals, and targets automotive body control modules requiring ISO16845-certified CAN communication.

For engineers reviewing the CY96F346RWBPQC-GS-UJE2 datasheet, CY96F346RWBPQC-GS-UJE2 pinout, CY96F346RWBPQC-GS-UJE2 application, or CY96F346RWBPQC-GS-UJE2 equivalent, key selection criteria include dual-clock reset configuration (RW suffix), 100-pin LQFP package, 2× CAN channels, 24 ADC inputs, and Flash security features for firmware protection in safety-critical embedded systems.

Technical Context

The CY96F346RWBPQC-GS-UJE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and hardware multiply/divide. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz internal RC oscillator-enabling independent clock sourcing for CPU and two peripheral domains (CLKP1/CLKP2).

Peripheral integration includes two ISO16845-certified CAN controllers (up to 1 Mbit/s, 32 message objects each), seven full-duplex USARTs with LIN master/slave capability, two I²C interfaces (400 kbps), and a 24-channel 10-bit ADC with dual reference voltage switching. The device supports 13 low-power operating modes and on-chip clock modulation for EMI reduction.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The CY96F346RWBPQC-GS-UJE2 achieves a maximum CPU frequency of 56 MHz using its on-chip PLL with an external 4 MHz resonator. This yields a minimum instruction cycle time of 17.8 ns, verified in the AC characteristics section (page 68) of Infineon's datasheet 002-04579 Rev. *C. The core maintains this performance across ambient temperatures from –40°C to +125°C under specified VDD conditions.

Does this part support LIN communication, and if so, how is it implemented?

Yes, the CY96F346RWBPQC-GS-UJE2 supports LIN 2.1 functionality through its seven full-duplex USARTs (SCI/LIN). Each USART can operate as LIN master or slave using dedicated baud rate reload timers and automatic sync-break detection. LIN frame handling-including checksum calculation and response scheduling-is performed in hardware without CPU intervention, reducing latency and firmware overhead.

How many CAN message objects does each controller support, and are they configurable?

Each of the two CAN controllers supports 32 independently configurable message objects. Each object has its own identifier mask, acceptance filtering, and transmit/receive buffer. Message objects can be grouped into programmable FIFOs for sequential processing, and interrupt masking is per-object-enabling selective event handling for priority-based CAN traffic management in real-time systems.

Is external memory expansion supported, and what interface options are available?

Yes, the CY96F346RWBPQC-GS-UJE2 supports external memory expansion via its multiplexed 8-/16-bit bidirectional data bus and up to 24-bit address space. It provides six chip select signals (CS0–CS5), programmable wait-state control, and external bus master capability. Timing parameters-including address setup/hold and data strobe-are fully configurable in the External Bus Interface register set for compatibility with SRAM, NOR flash, or FPGA peripherals.
